Water covers 71% of the Earth's surface. It is vital for all known forms of life. On Earth, 96.5% of the planet's
water is found in seas and oceans, 1.7% in groundwater, 1.7% in glaciers and the ice caps of Antarctica and
Greenland, a small fraction in other large water bodies, and 0.001% in the air as vapour, clouds (formed of ice
and liquid water suspended in air), and precipitation. Only 2.5% of the Earth's water is freshwater, and 98.8% of
that water is in ice (excepting ice in clouds) and groundwater. Less than 0.3% of all freshwater is in rivers, lakes,
and the atmosphere, and an even smaller amount of the Earth's freshwater (0.003%) is contained within
biological bodies and manufactured products.

Dry air consists of 78% nitrogen, 21% oxygen, 1% argon and other inert gases, such as carbon
dioxide. The remaining gases are often referred to as trace gases.

7. Effects of global war ming
Before
After
The potential dangers of global warming are being
increasingly studied by a wide global consortium of
scientists. These scientists are increasingly concerned
about the potential long-term effects of global warming
on our natural environment and on the planet. Of
particular concern is how climate change and global
warming caused by anthropogenic, or human-made
releases of greenhouse gases, most notably carbon
dioxide, can act interactively, and have adverse effects
upon the planet, its natural environment and humans'
existence.

8. LIFE
Plant Life Kingdom Animal Life Kingdom
Evidence suggests that life on Earth has existed
for about 3.7 billion years.[24] All known life
forms share fundamental molecular
mechanisms, and based on these observations,
theories on the origin of life attempt to find a
mechanism explaining the formation of a
primordial single cell organism from which all
life originates. There are many different
hypotheses regarding the path that might have
been taken from simple organic molecules via
pre-cellular life to photocells and metabolism.

9. What is an Eco-system ?
 An ecosystem is a community of
living organisms in
conjunction with the non-
living components of their
environment (things like air,
water and mineral soil),
interacting as a system.

10. Composition
The Earth's layered structure.
(1) inner core; (2) outer core; (3)
lower mantle; (4) upper mantle;
(5) lithosphere; (6) crust
Earth science generally recognizes 4 spheres, the
lithosphere, the hydrosphere, the atmosphere, and the
biosphere as correspondent to rocks, water, air, and life.
Some scientists include, as part of the spheres of the
Earth, the cry sphere (corresponding to ice) as a distinct
portion of the hydrosphere, as well as the exosphere
(corresponding to soil) as an active and intermixed
sphere. Earth science (also known as geoscience, the
geosciences or the Earth Sciences), is an all-embracing
term for the sciences related to the planet Earth. There
are four major disciplines in earth sciences, namely
geography, geology, geophysics and geodesy. These
major disciplines use physics, chemistry, biology,
chronology and mathematics to build a qualitative and
quantitative understanding of the principal areas or
spheres of the Earth.
